Checking the Core Version
Some maintenance operations require you to know the version of the currently installed HPE Ezmeral Data Fabricrelease (sometimes referred to as the "core version"). You can check the core version easily from within the Control System or Installer user interface or identify the version from your installed packages.
Checking the Core Version Using the Control System
The Control System displays the core version on the
Overview page:
To connect to the Control System, see Setting Up the Control System.
Checking the Core Version Using the Installer
If you used the Installer to install the cluster, you
can view the core version on the home page:
To set up the Installer, see Installer.
Checking the Core Version Using maprcli
Another way to view the currently installed core
version is to use the
maprcli dashboard info
command:cd /opt/mapr/bin
maprcli dashboard info -json
